Flip knives have a lot of configurations and a different principle of operation. It is quite possible to make such a tool yourself. To do this, you need to draw up a product drawing, for example, simply circling the contour from the finished knife. In addition, you will need the necessary material and appropriate equipment, as well as elementary skills in the work.
Preparatory stage
To make an automatic folding knife yourself, you need to take a strip of metal, transfer the sketch of the proposed product onto it. Then, using an emery or a special machine, you will need to process the future blade.
If there is no suitable device, then you should not even start manufacturing rather complicated products. Alternatively, you can use a file, a file or a hand drill for finishing . In addition, old kitchen knives are sometimes used as spikes .
After processing the blade and giving it the necessary shape, the part is clamped in yews and grinding begins. Initially, roughing is done with a diamond file, then finishing is carried out using a fine-grained block. The excess metal is sawn off, a hole is drilled in the center in the prepared part, the end face of the product is also processed by emery.

The next step is to make the handle. For this operation, a thin plate of titanium is quite suitable. Using an electric tool, we cut a rectangular workpiece of the desired size. It should be noted that titanium is a viscous material; when sawing, it is necessary to lubricate the treated areas with oil.
After preparing a pair of elements, we serve them on an emery machine. The ends of the blanks are brought to the same state by means of a file finish. Then we put the blade on the handle and clamp it with a clamp. Both halves of the handle are drilled through the central “window” of the tip.
You will also need to make a steel spring, which is processed according to the sketch. It is necessary to remove the chamfers from the outside of the holes, screw the slots for the button and the locking mechanism. After drilling the required holes, they are treated with a file to the required size. As clamps pads can be used bronze or brass bushings. They are placed in the side plates and riveted from the inside.
Assembly
Homemade throwaway knives at this stage acquire the desired shape and appearance. Elements for riveting are cut from nails or a suitable wire. After their installation, it is necessary to grind the edges to get a uniform surface.
Then, using a diamond file, a rectangular hole is made in the blade, and an axis is made using a lathe. Alternatively, you can do it with a file, but this process will be significantly longer in time. The latch and the working part are adjusted to each other by cutting rectangular sockets. The locking element of the U-shaped configuration is inserted into the handle of the product.
The spring sawn from steel is fastened with a bolt. If the whole procedure is carried out correctly, when you press the lock, the spring will act as a pusher. As this element, you can apply a similar spare part from a car starter. At the end of the process, the device is polished with a special paste to a mirror shine.
Final part
Making a folding knife with your own hands, you should take care of high-quality overlays. They are made of titanium, connected to each other and the blade by means of grooves and rivets, leading to a “salable” look by finishing with a file. The blade and axis are inserted, the working spring is cocked, the button is mounted, the pads are screwed together. We can assume that the automatic folding knife is ready.
The given instruction is an introductory material. Interpreting it to the available materials and imagination, any craftsman will be able to do a thing completely unlike analogues, which will rightfully be considered exclusive.
Features
If you decide to make your own knife with a folding blade for the first time, try to make the simplest sample first. As an example, a product from a dangerous razor is suitable. A similar instance is created from improvised materials, does not require special qualifications, has a minimum of details. But the finished product will look good along with the store counterparts, having all the necessary functionality.
Before starting work, you need to cut out patterns of blades and pens from cardboard or plywood. This will allow you to focus on the intended final sample. Then follows the fitting of all dimensions of a homemade blade. It will conveniently lie in your hand and will be cheap in terms of cost. Regardless of whether you plan to make a knife: folding front, folding or ordinary - you can use strong fabric, wood, horn or wood mushroom to decorate the handle.
What to look for
If you decide to make a knife with a folding blade yourself, certain difficulties may bring a search for decent material, especially the locking mechanism. For real masters, this problem fades into the background, but beginners will have to work hard. Alternatively, you can use a similar design from another product that has a working mechanism, but has lost its functionality or relevance.
Special difficulties will not make preparing a sketch, design, sawing a handle. With the right approach, the blade can also be machined quite quickly. The main working part in the form of a reliable fixing and ejection mechanism may require the lion's share of the time spent on making a homemade cutting tool.
Front ejection knives
This type of product has a more original principle of operation. The tip is thrown along the handle. Although this option is considered practical and effective, a more complex design often leads to breakdowns.
To remove this almost the only drawback, you need to carefully and reasonably approach the choice of product. In the case of self-production, you should choose practical and reliable components that are designed for a long service life.
User reviews
As evidenced by consumer feedback, folding knives are in demand and have several main areas of use. Despite the fact that such products are attributed to the accessory of individuals with a criminal past, “vykiduhi” are suitable for the following areas:
- utility work;
- hiking trips;
- long trips;
- hunting, fishing;
- military and special operations.
High-quality folding knife is made of strong and durable materials. The blade is best made of stainless high-strength steel. The handle can be made of plastic, wood or metal. Homemade and factory folding knives differ in appearance, characteristics, principle of operation and purpose. Among the wide range of these products, you can choose the appropriate instance, depending on the need.
To conclude the review
It is worth noting the existence of state requirements, which should be considered when choosing or manufacturing knives with a folding blade. A product with a blade, the length of which exceeds nine centimeters, is a cold type of weapon. Wearing it without special permission is a criminal offense.
Similar restrictions apply to all types of knives, regardless of the principle of their operation. You also need to properly care for the tool, which is expressed in regular sharpening, lubrication of moving parts. Proper maintenance will significantly extend the life of the device and increase its usefulness. Particular attention should be paid to the locking mechanism, which is considered the most vulnerable spot in folding knives and counterparts with front discharge.
